TWISTING AND DOUBLING MACHINE.

SPECIFICATION forming part of Letters'latent No. 410,297, dated September 3, 1889.

Application filed April 19, 1887. Serial No. 235,303. (No model.) Patented in England January 30, 1886, No. 1,383, and in 4 France December 6, 1886, No. 180,102.

To @ZZ whom it may concern;

Be it known that we, JAMES XVHALEY SHEPHERD, WILLIAM AYRToN, and RALPH CLEGG, all of Longsight, near Manchester, in the county of Lancaster, England, have invented a new and usefulV Improvement in Twisting and Doubling Machines,- of which the following is a specification, reference being had to the accompanying drawings.

The invention has been patented to us in Great Britain, No. 1,383, of January 30, 1886, and in France on the 6th of December, 1886, No. 180,102.

Our invention relates to machinery or apparatus for twisting or doubling, or twisting and doubling, slivers, yarns, or threads ot` cotton or other fibrous materials, certain portions of the apparatus being applicable for use in certain spinning-machines- Our invention relates to machines in which the sliver, yarn, or thread, or slivers, yarns, or threads, to be operated upon is or are wound upon a bobbin or spool, or bobbins or spools, and also to machines in which the sliver, yarn, or thread, or slivers, yarns, or threads, to be operated upon is or are wound in the form of a cop or cops, and to machines `in which the sliver, yarn, or thread, or slivers, yarns, or threads, after being operated upon, is or are Wound upon a bobbin or spool, and to machines in which the sliver, yarn, or thread,or slivers, yarns, or threads, after being operated uponis or are Wound upon a spindle in the form of a cop.

For convenience of description we will first describe the arrangement of spindle and certain apparatus immediately connected there with which We employ in those cases in which the sliver, yarn, or thread, or slivers, yarns, or threads, to be operated uponis or are Wound upon a bobbin or spool, and also the arrangement of spindle and certain apparatus immediately connected therewith which we employ lwhen the sliver, yarn, or thread, or slivers,

yarns, or threads, to be operatedupon is or are wound in the form of cops. Ve shall then describe the arrangement of machinery or apparatus which we employ in conjunction with the spindle when the sliver, yarn, or thread, or

slivers, yarns, or threads, operated upon is or li and Vfoot-step c.

are to be wound upon a bobbin or spool, and we shall then describe the arrangement of machinery or apparatus which We employ in conjunction with the spindle when the sliver, yarn, or thread, or slivers, yarns, or threads, 5 5 operated upon is or are' to be wound into the form of a cop.

We will describe our invention by reference to the drawings hereunto annexed, in which drawings- Figure 1 is a longitudinal section, Fig. 2 a side View, and Fig. 3 an end view, of a spindle carrying a bobbin on which the sliver, yarn, or thread, or slivers, yarns, or threads, to be operated upon is or are wound. Fig. tis a 65 longitudinal section, and Fig. 5 an end View, of a spindle carrying cops formed of the slivers, yarns, or threads to be operated upon. Fig. 6 is an end View, and Fig. 7 apartly-sectional side View, of a machine in which the 7o spindle is combined with mechanism by means of which the sliver, yarn, or thread, or slivers, yarns, or threads, after being operated upon, is or are wound upon a bobbin or spool.` Fig.

8 is a side View, Fig. 9 a plan, and Fig. 10 an 75 end View, of a drag or draw roller which is used in conjunctionwith the spindle above mentioned. Fig. 11v is a partial front View, and Fig. 12 an end view, ot a machine in which the spindle is combined with mechan- 8o ism by means of which the sliver, yarn, or thread, or slivers, yarns, or threads, after being operated` upon, is or are wound into the form of a cop. Fig. 13 is a View showing more clearly certain details shown in Fig. 12. 85

Fig. 14 is a view showing more clearly certain details shown in Figs. 11 and 12. Fig. 15 shows inplan cert-ain parts shown in elevation in Figs. 12 and 13. Fig. 16 is a plan, and Fig. 17 an elevation, showing, upon a larger 9o scale, portions of that Which is shown in Figs.

11, 12, and 13; and Fig. 18 is a plan, and Fig.

19 an elevation, showing certain parts which are partly, butimperfectly, shown in Figs. 11, 12, and 13. 95

1u Figs. 1 and 2, a. is a spindle mounted so as to be capable of being rotated in the collar Fast upon the spindle a is a warve d, by means of which the spindle a may be rotated. Te mount a tube eloose Ico` upon the spindle a.. To the tube e we attach a cradle or frame f. The lower portion f of the cradle or frame f is so formed that it will llO act as a weight and preventv the cradle or frame f from being rotated by the rotation of the spindle a. One edge' f2 of the cradle or frame f is formed curved. Longitudinally through a portion of the length of the spindle a we form a passage or tube g, which passage or tube g extends from the end a of the spindle a, to openings 7L, formed through the sides of the spindle a. Fast upon the spindle a we secure a cup j, and fast upon the boss of the cup ,j we mount a disk 7s. Upon the cradle or frame f we form a projecting part f3, which partly incloses the cup j.

The sliver or slivers and yarn or yarns and thread or threads to be twisted or doubled, or twisted and doubled, we shall, for simplicity, hereinafter call the yarn.

The yarn A to be twisted or doubled, or twist-ed and doubled, is wound upon a bobbin Z, which is placed upon the tube e. The yarn A to be twisted or doubled, or twisted and doubled, is conducted from the bobbin Z over the curved edge f2 of the cradle or frame f, then along the outer surface of the said cradle or frame f, and then over the end f4 ot the cradle or frame f to the end e of the tube e and along the passage or tube g, then through either of the openings 7L and over the edge 7s. of the disk It, from which the said yarn A passes to a drag or draw roller, as we will hereinafter describe. Vile provide the cradle or frame f with a ring f5, which prevents the yarn Afrom coming into contact with the bobbin Z. Then all the yarn wound upon the bobbin Z has been removed therefrom, such bobbin Z may be drawn oit' the tube e through the ring f5, and another bobbin having yarn wound thereon may be passed through the ring f5 and onto the tube c.

The yarn A to be twisted or doubled, or twisted and doubled, in its passage from the bobbin Z to the passage or tube g, formed in the spindle a, receives one amount of twist, and while passing from the spindle a to the drag or draw roller above mentioned receives a further amount of twist. The end e2 of the tube e passes into the interior of the cup j, and the part j et the cup j passes into a cavity formed by the projecting part f3 upon the cradle or frame f. The cup j and projecting part f3 prevent oil from the spindle d from getting upon the yarn A while such yarn A is being twisted or doubled, or twisted and doubled.

Figs. -l and 5 show an arrangement of our invention which we employ for twisting or doubling, or twisting and doubling, yarn which has been wound into cops. To the cradle or frame f we secure pegs or skewers m, upon which the cops B B are placed. At the end f4 of the cradle or frame f we attach guides 0 0,which are hinged to the cradle or frame f. The remaining ends of the guides 0 o are each formed with an eye o2. Vhen the guides 0 0 are turned upon the hinged part p, cops B B may be placed upon the pegs or skewers m, and after the cops B B have been placed upon the pegs or skewers m the guides 0 o may be again placed in the position in which they are shown in the drawings.

The yarn C to be twisted or doubled, or twisted and doubled, is passed from the cop B through the eye o2 of the guide o and from the cop B through the eye o2 of the guide o. The yarn C from both of the cops B B is passed through the passage or tube g and Veither of the openings Z7, and over the edge k of the disk 7c, as previously described in reference to the arrangement in which the yarn to be twisted or doubled, or twisted and doubled, is wound upon a bobbin Z. The yarn C from the cops B B will, by the rotation of the spindle a, receive one amount of twist in passing from the cops B B to the end d ot` the spindle ct, and in passing from the edge k ot the disk 7a to the drag or draw roller will receive an additional amount of twist. By means of the arrangements above described we are enabled to give to the yarn operated upon two turns of twist for every turn of the spindle employed.

Having now described the arrangement of apparatus by which we are enabled to impart to the yarn two turns of twist for each turn of the spindle a, we will now describe such apparatus as combined with certain other mechanism by means of which we wind the yarn upon a bobbin after it has been twisted or doubled, or twisted and doubled.

Figs. 6 and '7 show so much of a machine as is requisite to illustrate this application of our invention.

In Figs. 6 and 7, q r are end frames. To the end frame r is secured one end of each of the rails st, the remaining ends of which are secured to another frame similar to the framey r. The rails s t support the foot-steps c and collars b, which support the spindles a.. To the rails u Q1, which are secured at one end to the end frame r, We secure troughs w in which are shafts y z, respectively capable of being rotated in bearings, one only of which bearings is shown in the drawings. Upon the shafts y z grooved pulleys l are secured. 2 is a tin drum, which is driven by means of a strap 3 from any convenient source of motive power. The spindles a are driven by means ot the bands 4, which pass around the tin drum 2 and warves CZ and partially around a tin drum 5, which is mounted upon a shaft ['6, mounted in suitable bearings mounted upon the end frames of the machine, and acts as a guide to the bands 4.

Upon the axle 2a of the tin drum 2 is a wheel 7, the teeth. of which take into or engage with the teeth of a wheel 8, carried upon a stud 9. Secured to the wheel S is a wheel 10, the teeth of which gear into or engage IOO IIO

with the teeth of a `wheel 11, mounted ,upon a shaft 12, extending lengthwise of the machine.

13 is a shaft extending lengthwise of the machine, which shaft 13 receives rotary motion from the shaft 12 by means of the crossshaft 14 and bevel-wheels l5 16 17 18.

Fast upon the shaft 13 is a bevel-wheel 19, the teeth of which gear into or engage with the teeth of a bevel-wheel 20, fast upon the lower end of a vertical shaft `21, supported by brackets. Fast upon the upper end of the vertical shaft21 is a bevel-wheel 22, the teeth of which gearinto or engage with the teeth of a bevel-wheel 23, fast upon a horizontal shaft 24, which shaft 24 is carried in brackets. Upon opposite endsof the shaft 24 are bevelwheels 25 26, the teeth of which gear into the teeth of wheels 27 28, respectively mounted l by a set-screw 39 to the bracket 35.

fast upon the shafts 29 30, extending lengthwise of the machine. v

Above each of the spindles 31, which are supported by rails 32, is a drag or draw roller 33, fastupon a short shaft 34, capable of being rotated in a bracket 35, secured to the rail u or the rail. c, as the case may be. Fast upon the short shaft 34 is a bevel-wheel 36, the teeth of which gear into'or engage with the teeth of a bevel-wheel 37, fast upon the shaft 29 or 30, as the case may be. Beneath the drag or draw roller 33 is a iin ger 38, secured The drag or draw roller 33 and the finger 38 are shown more clearly in Figs. 8, 9, and 10, in which figures Fig. 8 is a side elevation, Fig. 9 a plan, and Fig. 10 a front view, of the drag or draw roller 33 upon an enlarged scale. The edge 38 of the finger 38 is formed inclined to the axis of t-he drag or draw roller 33. The rotation of the tin drum 2 will, by means of the wheels 7 8 10 1l, shaft 12, bevel-wheels 15 16, shaft 14, wheels 17 18, shaft 13, bevel-wheels 19 20, shaft 2l, bevel-wheels 22 23, shaft 24, bevelwheels 26 28 and 25 27, shafts 29 30,V bevelwheels 37 36, and short shafts 34, cause each of the drag or draw rollers 33 to be rotated in the direction indicated by the` arrow D. The yarn A from the bobbin Z, after being passed over the edge f2 of the cradle or framef, is conducted past the end f4 of the cradle or frame f, through the passage or tube g and one of the openings h, and over the edge 7c of the disk lo, from which it passes through a guide 40, secured to a bar 41, secured to the ltrough w or the trough as the case may be.

The yarn A then passes over one of the pulleys 1 and over a guide-rod 42 to the drag or. draw roller 33, around which and the finger 38 it is passed one or more times, as may be requisite. The yarn A is `then conducted under a taller-Wire 43, carried by a faller 44, to be wound upon the bobbin E, which is mounted upon a spindle 3l. The grooved pulleys l are driven bythe yarn or thread D passing over them.

Upon the shafts 12 13 are mountedtin drums 45, whiclnby means ofbands 46, impart rotarymotion; to the spindles 3l.`f 'The spindles 31 are rotated at a speed in excess of that required to take up the yarn delivered by the drag or draw .rollers 33 and drive or rotate the bobbins E by means of the frictionA between the flanges 31, upon the spindles 3l and the bases of the bobbins E, placed upon the said spindles 31. The inclined or curved edge 38'* of the finger 38 causes the yarn A, while being drawn from the bobbin Z, to pass around the drag or draw roller 33 in an open spiral and prevents one coil o yarn from f passing over a lneighboring coi The yarn is .passed as many tinls around the drag or draw roller 33 as/liay be requisite to draw the .yarn from the/bobbin Z.

The yarnf'is guided to or built upon the bobbins E by means of the faller-wires 43, which faller-wires 43 are actuated by means of the heart or cam 47. The heart or cam 47, which receives motion by means of the shaft 47, worm-wheel 47h, and worm 47c from the shaft 21, acts upon a bowl or roller 48, carried by a lever 49, connected by a rod 50 to alever 51, secured to a shaft 52, to which, the faller 44 is secured. l

To the lever 51 is jointed one end of a rod 53, which at its other end is jointed to alever 54, fast upon the shaft 55, upon which shaft 55 .is fastened an arm 56, which carries the faller-wire 43 on the opposite sideof the machine. The rotation of the heart or cam 47` impartsto the fallerfwires 43 the motion required to build the yarn A upon the bobbin E. If after the yarn has been twisted or doubled, or twisted and doubled, as above described, it is desired to wind such yarn upon aspindle in the form of a cop, We employ the arrangements shown in Figs. 11, 12, and 13.

To avoid confusion, certain parts are omitted from Figs. l1, 12, and 13. To such troughs w w, carrying shafts y z, upon which are mounted pulleys l. Upon the rails 1r/v are mounted drag or draw rollers 33. The rails s t u 'U are secured at their ends which are not shown in the drawings to an end frame similar to the end frame 58. j

59 60 are `rails which support4 spindles `61.

2 is a shaft which receives rotary motion from any convenient source of motive power. Upon the shaft 2 is mounted a tin drum 2, which imparts rotary motion to the spin-4 dles at by means of the bands 4, which bands 4 are guided upon the warves d of the spindles @by means of the tin drum 5. 62 are faller-wires carried by arms 63,

IOO

IIO

frame 58 are secured rails u n, which support mounted upon taller-shafts 64, supported in bearings carried by the end frame 58 and the other end frame of the machine.

65 is a counter faller-wire carried by arms 66, secured to a counter taller-shaft 67, supported by the end frame 58 and the other end frame of the machine.

68 is a shaft capable of being revolved in bearings carried by the end frames 57 58. Mounted upon the shaft 68 so as to be capable of being rotated thereon is a cone-drum 69, which receives rotary motion from the shaft 2 by means of the toothed wheels 63 64n 65 66a.

Fast with the cone-drum 69 is a toothed bevel-wheel 70, the teeth of which gear into the teeth of a bevel-wheel 71, carried by a bevel-wheel 72, mounted upon the shaft 68 so as to be capable of being rotated thereon. The teeth of the bevel-wheel 71 gear into the teeth of a bevel-wheel 73, mounted upon the shaft 68 so as to be capable of being rotated thereon. Fast with the bevel-wheel 73 is a toothed wheel 74, the teeth of which gear into or engage with the teeth of a wheel 75, mounted fast upon a shaft 76, mounted fast upon which is a tin drum 77, which, by means of endless bands 77, imparts rotary motion to the spindles 61.

78 is a shaft capable of being rotated in bearings formed in the end frames 57 58. Fast upon the shaft 78 is a cone-drum 79, which receives rotary motion from the cone-drum 69 by means of 'a strap 80. The cone-drum 79, the bevelwheels 7 9 and 7 9, short shaft 7 9,

' and bevel-wheel 79p imparu'motion to the bevel-wheel 72. The wheels 70, 71, 72, and 73 constitute a diierential motion, similar to that used in the machines known as roving or slubbing frames, by which differ ential motion the rotation of the tin drum 77 may be governed, as will be hereinafter described.

In the end frames 57 58 are formed bearings, supported by and capable of being revolved in which is a shaft 81, upon which are formed screw-threads 81m, mounted upon which and capable of being traversed thereon and thereby is a strap-guide 82, between the forked ends of which the strap 80 passes.

To one faller-shaft 64 is secured an arm 83, formed with a curved part 83, to the end of which is connected a chain 84, the other end of which is connected to a curved part 85, formed upon one arm 85 of abell-crank lever mounted so as to be capable of being oscillated upon a stud 86, carried by the end frame 58. One arm 87 of the bell-crank lever aforesaid is provided with a bowl or roller 88, which is supported upon a shaper bar or plate 89, carried upon a frame 90, capable of being slid longitudinally in V-guides 91, formed upon a bracket 92, secured to the end frame 58. Y rlhe frame 90 and certain of the parts connected .therewith are shown more clearly in Fig. 14, which will be hereinafter more particularly described in reference to a'further part of our invention. Secured to the frame 90 is a stud 93, which carries a bowl or roller 94, against which acts a cam 95, mounted fast upon a shaft 96, mounted so as to be capable of being rotated in bearings formed in the end frame 58. The shaft 96 receives rotary motion by means of the worm-wheel 97, worm 98, and bevel-wheels 99 100, the latter of which is fast upon the shaft 68. l As the cam 95 rotates it will, by means of the bowl or roller 94, cause the frame 90 to be slid to and fro in the brackets 92, and by'means of the shaper bar or plate 89, as will be readily understood by persons acquainted with machines for building yarn into cops, will by means of the bowl or roller 88, arms 87 85, chain 84, and arm 83 raise the taller-wires 62 upon one side of the machine and allow them to descend, so as to guide the yarn while being wound upon the spindle 61. The yarn A to be wound upon the spindles 61, after leaving the drag or draw rollers 33, passes beneath the counter faller-wires 65, and from the counter taller-wires 65 passes over the faller-wires 62, from which it passes to the spindles 61. The drag or draw rollers 33 deliver the yarn A to the spindles 61 at a uniform speed, and in order that the spindles 61 may take up the yarn A as it is delivered by the drag or draw rollers 33 we employ the arrangements to be next described, by means of which arrangements the speed at which the spindles 61 are rotated maybe increased or decreased, as may be required,.in order to wind the yarn A into cops upon the spindles 61. In order that this IOO portion of our invention may bev readily un- Y derstood we showin Fig. 13 certain parts in positions different from those in which they are indicated in Figs. 11 and 12. The counterfaller 66 is weighted, so that it tends to turn in the direction indicated by the arrow F by means of a weight or spring, (not shown in the drawings,) which weight or spring is proportioned to the tension required in winding the yarn upon the spindles 61.

Fast upon one of the faller-shafts 64 are arms 101 102, to which are jointed catches 103 104, respectively. Fast upon the catch 103 is j a lever 105, and fast with the catch 104 is a lever 106. To the lever 105 is jointed one end of a rod 107, the remaining end of which is jointed to a rod 108. To the lever 106 is jointed one end of a rod 109, the remaining end of which is jointed to a rod 110. Thelower ends of the rods 108 110 pass through holes formed through a bracket 111, which bracket 111 acts as a guide for the said lower 'ends of the rods 108 110. Fast upon the shaft 81 are two ratchet-wheels 112 113, placed side by side, the teeth of which ratchet-wheels 112 113 are placed in opposite directions. The ratchet-wheels 112 113 are shown in the detached view, Fig. 15.

Near to the lower end ofthe rod 108 is jointed a catch or pawl 114, the weight of which at certain times, as will be hereinafter pointed out, causes the catch or pawl 114 to engage with the teeth of the ratchet-wheel112. Nearv IIO ' wheel 113.

to the lower end of the rod 110 is jointed a catch or pawl 115, which catch or pawl 115 is caused at times, as will be hereinafter pointed out, to engage'with the teeth of theratchet- At. the upper end of the rod 108 is formed a tooth 116 and at the upper end of the rod 110 is formed a tooth 117.

To the endt'rame 58 is secured a stud 118, upon which and capable of being oscillated thereon is a boss 119, upon which are formed arms 120 121 122. To the end frame 58 is secured a stud 123, upon which and capable of being rotated thereon is a boss, to which is secured a toothed wheel 124, which receives rotary motion by means of the wheel125, fast wit-h which is a wheel 125, which gears into a wheel 681, fast upon the shaft 68. Upon the stud 123 and fast with the toothed wheel124 is mounted a cam 126, which acts upona bowl or roller mounted upon the arm 121, fast upon the boss 119. As the cam 126 rotates, the arm 121 will be oscillated by means of the cam 126 in the direction indicated by the arrow G and will be oscillated in a direction opposite to that indicated by the arrow G by meansof a spring 127, one end of which is secured to the arm 120, the remaining end of the spring 127 being secured to the end frame 58.

Upon the extremity of the arm 120 is formed a tooth 128, which at times, as will be hereinafter pointed out, is caused by the oscillations of the arm 120 to act upon one or other of the rods 108 110, so as to draw it in the direction indicated by the arrow H. Fast upon the shaft 96 is a disk 129, a portion of the circumference of which disk 129, between the points J and K, is removed in order that a recess, into which may pass a bowl carried by the arm 122, may be formed. Secured to the end frame 58 is a stud 130,

4 mounted upon which so as to be capable of being` oscillated thereon is a bellcrank lever, one arm 131 of which is in Acontact with the circumference of a cam 132, mounted upon the stud 123 and fast with the toothed wheel 124.A The arm 133 of the bellcrank lever aforesaid is situated beneath the ends of the levers 105 106, and at certain times, as will be hereinafter pointed out, will raise the ends of the said levers 105 106, and with them the ends of the rods 108 110. When the machine above described is at work, the yarn A, in its passage from the bobbinsl to the drag or draw rollers 33, will have been twisted or doubled, or twisted and doubled, as hereinafter described, and will by the rotation of the spindles 61 be woundthereon. So longasthe yarn A is wound upon the spindles 61 at the same rate as it is delivered by the drag or draw rollers 33, thecounter taller-wires 65, byrising and falling between the points L and M, will compensate for the variations of the rate at which the yarn A is wound upon the smaller Vor larger part-s of the cop. lt' the yarn A be taken up by the spindles 61 at a rate greater than that at which it is delivered by the drag or draw rollers 33,'the counter taller-wires will be caused to arrive beyond the point M, and by means of an arm 134, rod 135, and arm 136 turn 'a'` part 137 in the direction indicated bythe arrow N, and so more the part 137 from beneath the catch 103, when the rod 107, being no longer supported, will descend and bring the tooth 116 into the path of the tooth 128, so that each oscillation of the arm 120 in the direction opposite to that indicated by the arrow G, will be caused to draw the rod 108in the same direction, and by means of the catch or pawl 114 and ratchet-wheel 112 rotate the 'shaft 81, and by means of the screw-threads formed on the said shaft 81 traverse the Astrapguide 82 and the strap 80 from a larger to a smaller part` of the cone-drum 69, and by means of the cone-drum 79, bevel-wheels 79 79, shaft 79, bevel-wheels 79p 72 70 71 7 3, wheels 74 75, shaft 76, and tin drum 77 reduce the speed of the spindles 61,' and thereby, reduce the'rate at which the yarn A is wound upon the spindle 61.v The reduction of the rate at which the yarn A is wound upon'the spindles 61 will allow the counter taller-wires 65 to descend to their normal position. The oscillations of the arm 133, caused by means of the cam 132, will `lift the catch 103 to the level of the top of the part 137, and as soon as the descent of the counter fallerfwires 65 turnsthe part 137 into position to support the catch 103 the tooth 116 will be raised clear of the ltooth 128 on the arm '120. It the yarn A be taken upv by the spindle 6l at a rate less than that at`which it is'delivered by the drag or draw rollers 33, the counter taller-wires 65 will descend below the point L, 'and will by means of the arm 134, rod- 135, 'and arm 136 put the part 137 clear of the catch 104, and thus allow the ar1n`134, rod 109, and rod 110 to descend and allow the tooth 117 to pass into the path of the tooth 128 upon the arm 12'0, which, being oscillated by the cam 126, as hereinbefore described, will, when moving in the direction opposite to thatV indicated by the Aarrow G, draw forward the rod 110 in the direction indicated by the arrow H, and by means of the catcher pawl 115 and ratchet-wheel 113 andscrewthreads formed upon theA shaft 81 will traverse the strap-guide 82,V so as' to traverse the IOO IIO

strap 80 from asmaller to a larger part of the; o

cone-drum 69, and by'means of the cone-drum 79, bevel-wheels 7 91 7 9, shaft 79, bevel-wheels 79D 72 70 71 73, wheels 74 75, shaft 76, and tin drum 77 cause the spindles 61 t-o rotate with an increased velocity, and by so doing wind the yarn A upon the spindles 61 'at a greater rate. The increase in the rate `at which theyarnA is wound upon the spindles 61 will Acanse the Vcounter faller-wires 65 to ascend totheir normal position,so ask to turn the part 137 into position to support the catch 104,1od109, and rod 110, and the tooth 117,.ha`vi1ig Lbeen raised by the 4cam 132 and arrn133 of the bell-crank 4lever aforesaid, will also haveL raised therodJ 'ai1d tooth 117 clear' of the toot-h128`on the arm 120, and the ratchet-wheel 113 will cease to be acted upon. The weight of each of the rods 108 110 causes it to move in the direction opposite to that indicated by the arrow H. The movement of the rods 108 110 in the direction opposite to that indicated by the arrow H is limited by means of projections 108n 110, formed upon the rods 108 110, respectively. The disk 129 is fixed in such position upon the shaft 9G that the recess between the points .T and K arrives opposite the bowl on the arm 122 at such times only as the taller-wires G2 are at about half of their lift between the largest and smallest parts of the cop. Vhen the bowl on the arm 122 is in contact with the part of the circumference of the disk 129 situated between the points-K and J, and the bowl on the arm 121 is held clear of the cam 126, no motion is imparted to the rods 108 110. The fallerlshaft G4 on one sidev of the machine,by means of the arm 138 and chain 139 and arm 140, actuates the fallershaft G4 and taller-wire G2 at the other side of the said machine, and the counter fallershaft G7 at one side of the machine, by means of the arm 141, chain 142, and arm 143, actuates the counter taller-shaft 67 at the other side of the said machine.

A further part of our invention consists in an arrangement of copping motion, to be used in conjunction with the abovedescribed or any other arrangements of machinery or apparatus for twisting or doubling, or twisting and doubling, slivers, yarns, or threads. This portion of our invention is shown in Figs. 11, l2, and 14. In Fig. 14 our arrangement of copping motion is shown separated from the other parts of the machine. 90 is aframe supported by V-guides 92, in which it maybe slid lon gitudinallyin the direction indicated by the arrow O by means of the cam 95, which acts against the bowl or roller 94 upon the stud 93, projecting from the frame 90. The frame 90 maybe traversed in a direction opposite to that indicated by the arrow O by means of a weight or spring. (Not shown in the drawings.) Supported by the frame 90 are two inclines 144 145, which are formed with parts 146, which embrace V-guides 147, formed upon the frame 90. Formed upon the frame 90 is a boss 148, through which passes a short shaft 149, capable ot being rotated in the boss '148 and prevented from moving longitudinally by collars. Upon part of the short shaft 149 are formed screw-threads 150, which take into or engage with screw-threads formed in a part 151, secured to the inclines 144 145. Mounted upon the short shaft 149 is a ratchet-wheel 152. Formed upon or secured to the frame 90 is an arm in which is formed a slot 153. 89 is a shaper bar or plate, which is provided with projecting parts 154 155, by which such shaper bar or plate 89 is supported uponthe inclines 144 145. The projecting part 154 passes into the slot 153. As the frame 90, above mentioned',is moved to and fro by the cam 95 and weight or spring above referred to, the Shaper bar or plate 89 is traversed below the bowl or roller 88, carried by the arm 87, which, by means of the chain 84, actuates the taller-shaft 64. As the frame 90 is caused by the cam 95 to traverse to and Jfro, the ratchet-wheel 152 is caused to be rotated by means of the bell-crank lever 15G and clicks or pawls 156n carried thereby, as will be well understood by persons conversant with the machines known as self-acting mules. Secured to the bracket 92 is a bracket 92m, the upper edge of which is formed with an incline 92. When the arm of the bell-crank lever 15G resting upon such incline 92n is traversed along said incline by the movement of the frame 90 in a direction opposite to that indicated by arrow O, the pawls or clicks upon the bell-crank lever 156 will cause the ratchet-wheel 152 to be turned. The rotation of th'e shaft 149 will, by means of the screw-threads 150, cause the inclines 144 145 to be moved upon the frame 90 in the direction indicated by the arrow P, thus causing the shaper bar or plate 89 to be raised and act upon the taller-wire 62, so as to cause a cop to be built or formed in the form desired, the form of the cop being controlled by the contour of the shaper bar or plate 89 and those of the inclines 144 145.

lf it be desired, a still further amount of twist may be imparted to the yarn after such yarn has left the drag or draw roller above mentioned by the employment of an ordinary ring traveler and spindle for taking' up' the yarn delivered by the before-mentioned drag or draw roller; or a spindle and Hier may be used for the same purpose.

In some cases, when the yarn, after being twisted or doubled, or twisted and doubled, by any of the above-described arrangements, is wound upon a bobbin or tube by means of any of the arrangements ordinarily employed in drum-winding machines, the drag or draw roller above mentioned maybe dispensed with.

ln some cases we form the disks k, hereinbefore mentioned, with eyes or curls, through one of which the sliver, yarn, or thread being operated upon may be passed, and in some cases we employ arms instead of disks 7c, which arms may be formed with eyes or curls,through which the sliver, yarn, or thread being operated upon may be passed.
